The bond angle is 180 because ICl2- has three Lone Pairs attached to it making it Linear.
The question is nonsense. WHICH bond angle? There are many of them in a molecule the size of estradiol.
The bond angle of BF2 is 120 degrees.
The value of the bond angle in XeF2 is 180 degrees.
90 degrees is the value of the smallest bond angle in IF4.
The bond length is equal to the linear distance between the nuclei of the bonding atoms. The bond angle is equal to the angle between any two consecutive bonds in a molecule or ion. Bond angles of molecules and ions are usually determined by using the VSEPR theory.
ICl2 is isostructural with IBr2. Both molecules have a linear shape with an I-X-I bond angle of 180 degrees, where X represents the halogen atom.
